Hello every one 

I have a small issue which is How to exclude some industry from my sample ?

as we know that SIC variable consists of numbers and alphabets (e.g., K1, G05, .. etc) 

when i use IF sentence 

data real; set rem;
if SIC=j66  then delete;
run;

it does not work 

i get this message 

NOTE: Variable j66 is uninitialized.

please how can do it

If you don't put quotes around a value then SAS assumes it is a variable hence the note about the variable not initialised:

data real; set rem;
if SIC='j66'  then delete;
run;

You need to put the string J66 in quotes exactly as it appears in the data:

data real; 
set rem; if sic='J66' then delete; run;

Or what may be quicker:
 

data real; 
set rem (where=(sic ne 'J66')); run;
